The following two are just for fun. In 2005 Chen Kaige shot Wuji, which cost a huge amount of money but turned out to be a really crappy one. A netizen used some of his movie clips to make a humorous story named A Story of Murder Originated from A Piece of Bread, and then posted it on internet. The latter, aimed at making fun of Wuji, got millions of clicking from China and abroad. Chen was mad at the netizen and even threatened him with a litigation.
